** __Physical and Chemical Parameters__ **
Every monitoring visit measured basic physical and chemical parameters of Long Island Creek sites 5A and 5B which, according to GA-Adopt-A-Stream (AAS), allows for "specific water quality characteristics" to by analyzed. According to AAS, basic physical parameters include air and water temperatures, relative humidity, and water conductivity. Chemical data includes pH, dissolved oxygen (mg/L), nitrate-nitrogen (mg/L), and phosphate (mg/L).

Long Island Creek site 5B data collection was carried out three times at the same location, once a week over a period of three consecutive weeks in June approximately at the same time in the early afternoon. Overall, physical and chemical data collected remained stable and within a healthy stream range. Indicated below, pH levels for LIC5B averaged at 6.83 every during every site visit. This level of pH approximates the neutral level of pH 7, which falls under the "optimal range for most aquatic organisms" (GA-AAS Complete Manual) of pH 6.5 to pH 8.2.
 * __Data Collected__ **



The average conductivity level was 140 us/cm, which remains within the 0 to 1500 us/cm levels of rivers in Georgia and within the 50 to 500 us/cm range of inland "streams supporting mixed fisheries".Nitrate-nitrogen and and Phosphate tests were carried out in the lab after every water collection and as the table below demonstrates, neither nutrients were present at Long Island Creek site 5.



Air temperature ranged between 26 and 27.5 degrees Celsius, with an average of 26.83 degrees Celsius between all monitoring visits. Relative humidity measured an average of 55% during monitoring. . Water temperature and dissolved oxygen results can be observed below. Water temperature remained stable during data collection with an average of 23.33 degrees Celsius and dissolved oxygen averaged at 6.52 ppm, which ranged at a healthy level to support most aquatic organisms (GA-AAS Complete Manual).
